Abstract (en)
[origin: WO2012078322A1] Polyurethane elastomers are formed by curing a reaction mixture containing at least one polyisocyanate at least one polyol, an aliphatic diol chain extender and a small amount of a secondary amino compound that may have none or one or more hydroxyl groups. The reaction is catalyzed with a metal catalyst. In certain embodiments, the catalyst is an organozirconium, organotitanium or tertiary amine-based catalyst. The presence of the secondary amine compound in those cases provides for a good surface appearance and good physical properties.
